Pots
There will be 4 pots. Since there is no reigning title holder, the pots will be ranked by serie level first and previous season's results second. While normally there would be 4 pots of 8, we happen to have 10 new members in Serie C this season who would essentially be tied in rank. So instead, Pot 4 will contain all 10 serie c teams, and only 6 teams will be in Pot 3 (info on how this affects the draw later on). So here are the pots:

Draw Sequence
With the World Cup draw, they draw a team and a slot (1-4) within the group. Since the schedule is already set for each slot within each group, and I don't want to draw group slots when I draw each team, a quick random draw of the of the slot order will be done for each group beforehand. This is done so that certain pots aren't guaranteed 2 home games and further randomizes the playing order within the group. So for example, I'll randomize Group A and it may turn out that slot 1 goes to the 3rd team drawn, slot 2 to the 1st team drawn, etc. Hopefully that makes sense, and if not, don't worry, it's not that big of an issue and will make more sense later on. It's just to randomize the matches.

After that, the teams will be drawn. First, the pot 1 teams will be drawn group-by-group. Then the same for pot 2. At this point, 4 groups will have 2 serie A teams, and 4 will have an A and B team. To ensure each group contains a member from each Serie, two of the A/B groups will be drawn with a team from Pot 4 (Serie C). Then, the draw will continue on as normal, with the Pot 3 teams drawn group-by-group, and then the 8 remaining Pot 4 teams drawn last.

The first group matches will open the same day as Matchweek 2 (which I'd assume is set for Saturday, Oct. 15).

Now, to ensure each group has each Serie represented, 2 teams from Pot 4 will be drawn and randomly assigned to one of the four groups already containing an A and B squad. They will be entered into the Pot 3 slot...
